Answer:
20.36
Step-by-step explanation:
The area of the whole circle is pi*3.6^2 = 40.715 (rounded). However, the shaded portion is only half of the circle, since the arc is 180 degrees, so we divide this by 2 to get about 20.36.
Answer:
13
Step-by-step explanation:
3x13-4=35 Hope this helps
Consecutive integers are numbers in a row on a number line (ie. 4,5,6 or 457,458,459 or 12341, 12342, 12343). They can also be negative as long as the problem doesn't specify if it's positive.
x= first integer
x+1= second integer
x+2= third integer
x+3= fourth integer
Add the four integers equal to 354.
x + (x+1) + (x+2) + (x+3)= 354
combine like terms
4x + 6= 354
subtract 6 from both sides
4x= 348
divide both sides by 4
x= 87 first integer
THREE REMAINING INTEGERS
x+1= 87 + 1= 88 second integer
x+2= 87 + 2= 89 third integer
x+3= 87 + 3= 90 fourth integer
ANSWER: The four consecutive integers are 87, 88, 89 and 90.

Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
= 
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
